Selective dissolution of amorphous and nanocrystalline Zr2Ni
Source abstract
Abstract
Rapidly quenched Zr2Ni amorphous and nanocrystalline ribbons were subjected to electrochemical selective dissolution. The porous structure of the dealloyed materials showed a dependence on the alloy microstructure. The etching takes place with constant rate in three dimensions, indicating a surface controlled dissolution process. The etching rate of the amorphous alloy was found to be lower than for the nanocrystalline material. Partial crystallization of the de-alloyed amorphous ribbon has been observed. The electrocatalytic activity for Hydrogen evolution reaction of the selectively dissolved amorphous and nanocrystalline ribbons was found to be improved compared to the as-cast alloys.
